From 4dae99638097b254c863c541368598f5a80e41bf Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 26 Jun 2013 16:30:41 -0700 Subject: [PATCH] USB: legotower: remove custom debug macro and module parameter Now that we don't use the dbg() macro, remove it, and the module parameter. Also fix up the "dump_data" function to properly use the dynamic debug core and the correct printk options, and don't call it twice per function, as the data doesn't change from the beginning and the end of the call.
